MR c5: Regional Materials
To increase demand for building materials and products that are extracted and manufactured within the region, thereby supporting the use of indigenous resources and reducing the environmental impacts resulting from transportation.
Use building materials or products that have been extracted, harvested or recovered, as well as manufactured, within 500 miles of the project site for a minimum of 10% or 20%, based on cost, of the total materials value. If only a fraction of a product or material is extracted, harvested, or recovered and manufactured locally, then only that percentage (by weight) can contribute to the regional value. The minimum percentage regional materials for each point threshold is as follows:
Mechanical, electrical and plumbing components and specialty items such as elevators and equipment cannot be included in this calculation. Include only materials permanently installed in the project. Furniture may be included if it is included consistently in MR Credit 3: Materials Reuse through MR Credit 7: Certified Wood.
Potential technologies & Strategies
Establish a project goal for locally sourced materials, and identify materials and material suppliers that can achieve this goal. During construction, ensure that the specified local materials are installed, and quantify the total percentage of local materials installed. Consider a range of environmental, economic and performance attributes when selecting products and materials.
Use local construction material (or called Regional material)
Total cost of Regional materials compared with total construction materials cost) is more than 30%
(Local materials: Rebar steel, steel structure, concrete, insulation, gypsum, bricks, cement, aluminum, sands, stones, wire mesh, glass).
Use regional material to supporting the regional economy and reducing the environmental impacts resulting from transportation.
More than 30% of the total building materials value includes materials and products that have been manufactured and extracted within 500 miles of the project site or materials or products shipped by rail or water that have been extracted, harvested, or recovered, as well as manufactured, within a 500 miles (800 kilometers).
Total travel distance from the project site using a weighted average determined through the following formula: (Distance by rail/3) + (Distance by inland waterway/2) + (Distance by sea/15) + (Distance by all other means), which is less than or equal to 500 miles (800 kilometers).
